--input and --output parameters to rust sbp2json, json2json, json2sbp

JIRA Reference

https://swift-nav.atlassian.net/browse/DEVINFRA-738

[adrian-kong]

is there a way to make clap do without the -- parameter? i just saw the comment on the ticket, would it have to instead use std::env::args hmm

yeah if you don't specify long/short it should be a positional argument instead of a flag

[silverjam]

Need to update these example usage strings since we're not using option args (using positional args instead), example:

json2json [<INPUT> [<OUTPUT>]]

[notoriaga]

What does --help show if we remove that completely? I feel like that's pretty similar to what clap will generate anyway

[silverjam]

Yeah, probably better to just remove this
